SYRACUSE, N.Y. -- The site of a quadruple shooting early Sunday morning calls itself "Hush Lounge" but operates out of a boarded-up upholstery business. There isn't a sign, and the windows are boarded up.

Police are "looking into" whether the site is operating legally, said spokesman Sgt. Richard Helterline.

Four people were shot and suffered non-life-threatening injuries at a shootout around 3 a.m. At least two guns were fired, and there were at least 10 gunshots, police said.

The shooting began after a "large fight" inside and outside the lounge, and bullets sprayed across East Fayette Street. The fallout was visible early Sunday morning: Bloody footprints and a Honda SUV damaged by gunfire.

Helterline said police are still investigating the circumstances behind the shooting. He also said the lounge has drawn investigators' attention.

They'll be looking into whether the lounge was serving alcohol. They would not be able to do so after 2 a.m. It was not immediately clear whether the lounge had a liquor license.

This screenshot from Facebook appears to show the inside of Hush Lounge, which operates out of a boarded-up upholstery business. Kawan Woodley, an owner, posted this picture from "teen night" about 11:30 p.m. on Friday.

"(Hush is) a place that hosts after hours events at times, and depending on what they are doing it may or may not be legal," Helterline said. "We are looking into it. They would not be able to serve alcohol there without a permit, and surely not after 2 a.m. At this time we do not know if they were serving or not."

The lounge could be operating legally if it does not serve alcohol, Helterline said.

"If they just have people over, then it may not be breaking any laws," he said.

The New York State Liquor Authority's website has no record of a liquor license at the address.

The site at 1226 E. Fayette is a boarded-up upholstery business called "Silverbush." On Sunday morning, the site was too dark to see inside except for a cigarette butt that sat inside on a windowsill.

Helterline said he was not sure if the upholstery business still operated.

Business records in Syracuse.com archives show a Hush Lounge was incorporated in 2014 on 1200 E. Fayette Street by Kenneth Kinsey and Kawan Woodley.

Woodley and Kinsey could not be immediately reached Sunday.

Woodley's Facebook page shows lively scenes at what he called "Hush Lounge" in recent days, including a post from Friday night around 11:30 p.m. for "teen night."

"Hush lounge teens rocking better then (sic) the adults," he wrote in the post, accompanied by a blurry picture or people dancing.

A neighbor who witnessed the shooting and heard about 10 gunshots early Sunday called the place a nuisance. He said he'd called 911 on it in the past. The neighbor declined to be identified out of fear of retaliation.
